I have installed fresh Ubuntu Mate 17.10 - Artful Advark.

This is my Intel configuration file:

$ cat /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
    Identifier  "Intel Graphics"
    Driver      "intel"
    Option      "TearFree"    "true"
    Option      "AccelMethod" "sna"
    Option      "DRI"         "3"
EndSection

I have installed latest available drivers using Intel Graphics Update Tools for Linux

Because tool wasn't able to run on 17.10 I temporary changed /etc/lsb-release to corespond 17.04 Zesty Zapus and then I successfully installed drivers using tool.

After all this trouble I often have issues. My screen randomly goes black for 10 seconds because of GPU HANG. Also sometimes elements flicker in programs which use HW acceleration (mostly chrome, disabling hardware acceleration is not an option because chrome works terrible)

Here is crash dump

VGA adapter info:

$ lspci | grep VGA

  • " Please file a new bug report on bugs.freedesktop.org against DRI -> DRM/Intel" so do that... we can't help you ;) – Rinzwind Oct 29 '17 at 20:29
  • I saw that, there is already an BUG report, a few of them actually. I even found bug report from 2016 (so still isn't fixed, but i didn't have problems on 17.04). If someone with more knowledge than me could look at crash dump maybe it's something easy to fix. – Luka Oct 29 '17 at 20:30
  • I filled another bug report if it's of any help bugs.freedesktop.org/show_bug.cgi?id=103509 – Luka Oct 29 '17 at 20:39

I got similar trouble for 3 months ! (I need to use my win***z to check HW failure. No problem with my M$ spare wheel

But after many, many search on the web

I find it's two accel mode (at least) for this graphic card sna or uxa So, first of all, I need to (re)install the intel driver

sudo apt install xserver-xorg-video-intel

and create/modify the

/etc/X11/xorg.conf.d/20-intel.conf

with these options

Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" #Option "AccelMethod" "sna" EndSection

You can find more info about intel graphics card options at wiki gentoo

You need to reboot and try

  • So which one are you using? I'm using sna If I switch to Uxa, that solves the GPU hang? Cuz I'm still experiencing this. Even though intel staff on free desktop said they "fixed" they have no clue. obviously. I keep updating kernel and hoping for miracles xD – Luka Feb 7 '18 at 12:20

    I switched to UXA and I kept the DRi 3 I will see if the bug pops again. But performance is worse. I would rather restart lightdm every 20 minutes than suffer this performance loss. – Luka Feb 7 '18 at 13:00
